Kanye West has urged his fellow musicians to boycott Arizona over the U.S. state's controversial new immigration legislation - calling on artists to follow in the footsteps of civil rights icon Rosa Parks.Rage Against The MAChine frontman Zack De La Rocha is leading a campaign against Arizona's recently passed law, which makes failure to carry immigration documents a crime. Cypress Hill, Juanes, Massive Attack, Jack Black, filmmaker Michael Moore and De La Rocha's bandmates have also joined the campaign. And West is backing the action, insisting performers should not play any shows in the state as a mark of protest - comparing it to civil rights activists who boycotted buses in Alabama after African-American Parks refused to give up her seat to a white passenger in 1955. The Stronger hitmaker says, "When Rosa Parks refused to give up her seat, they arrested her. As a result, people got together and said, 'We are not going to ride the bus until they change the law.' It was this courageous action that sparked the Montgomery bus boycott. "What if we got together, signed a collective letter saying, 'We're not going to ride the bus', saying 'We are not going to comply. We are not going to play in Arizona. We are going to boycott Arizona?!'"
